Chapter 5: Creating and Editing Primitive Objects

Tutorial: Adding stairs to a clock tower building
I’ll leave the architectural design to the architects, but for this example, you’ll create a simple staircase and
add it to the front of a clock tower building.
To add stairs to a building, follow these steps.
1. Open the Clock tower building.max file from the Chap 05 directory on the DVD. This file
includes a building with a clock tower extending from its center, but the main entrance is empty.
2. Select Create ➪ AEC Objects ➪ Straight Stair. Click and drag in the Top viewport from the loca-
tion where the lower-left corner of the stair is located and drag to the upper-left corner of the
stairs where the stairs meet the entryway into the building to set the stair’s length. Then drag
across to set the stairs’ width and click at the opposite side of the entryway. Then drag downward
in the Left viewport to set the stairs’ height and click. Then right-click in the Top viewport to exit
Stairs creation mode.
3. With the stairs selected, click the Select and Move (W) button in the main toolbar and drag the
stairs in the Front viewport until they align with the front of one side of the entryway.
4. Open the Modify panel, and select the Box option in the Parameters rollout. Then adjust the
Overall Rise value so it matches the entryway.
5. Select Tools ➪ Mirror, and select the Copy option with an Offset of around –140 about the
X-Axis. Click OK.
Figure 5.30 shows the clock tower building with stairs.
